Illegal type for StackMapType: 12

[fjcarretero]

Hi,

I have been making a PoC with graphql for a project. 

I have seen that graphql uses underneath RefectASM (version 1.11.3) and I have a problem. Simplifying, in graphql, you define a method in a file to retrieve data. GraphQL uses RelectASM to call this method. For what I have seen, ReflectASM generates a class to make more efficient this reflection call.

My application is based on Spring, and it uses spring-instrument (aspectjweaver) as a java agent. This class generated by ReflectASM, is passed through the agent and is throwing that exception ("Illegal type for StackMapType: 12")

This is the relevan stacktrace:

I'm afraid it's hard to tell which library is at fault. It would help if you could simplify the problem as much as possible.
